One guy in England created the MMR regret movement by telling parents MMR gave their kids autism. People will believe all kinds of stupid things if you give them a simple answer to a complex question and promise a solution to a problem, especially if you appeal to their vanity and tell them they know something the experts don't. Once serious COVID becomes rare enough that the cost of
not vaccinating is forgotten, the antivax movement will become even more widespread than it is now.
On the other hand, as the vaccines are normalized and the predictions of mutant babies and mass goy culling don't actually happen, maybe the antivaxers will forget about them and find something else to concentrate on. I remember a lot of them dropping the MMR thing when the HPV vaccine came out and they all decided it would either kill sterilize their daughters, turn them into turbosluts, or kill them on the spot. When that didn't happen, they were kind of quiet until COVID came along.
As a reminder to antivaxers, vaxies
make more money than you, are
better educated than you, and
live longer than you, even when you exclude COVID as a cause of death. We are also better looking.
